て従来は次のような問題が発生していた。 FIG. 1 shows a lighting circuit for a conventional high-pressure discharge lamp with a built-in starting device. A second bimetal switch 3 and a resistor 5 are connected in parallel with the discharge tube 1.
are connected in series and housed in a common outer sphere 6. When a high-voltage discharge lamp having such a configuration is connected to a power source 8 via an inductive ballast 7, a current is first passed through the ballast 7 and flows through the series body of the second bimetal switch 3 and the resistor 5. The flow resistor 5 becomes red hot. The second bimetal switch 3 is heated by the red heat of this resistor 5 and opens after a few seconds, but at that moment, the current flowing to the ballast 7 is suddenly cut off, so the ballast 7
A pulse voltage is induced. This pulse voltage, in addition to the starting assisting effect of the starting assisting conductor 4 provided on the outer surface of the discharge tube 1, starts the discharge of the discharge tube 1. Even after the discharge of the discharge tube 1 starts, the second bimetal switch 3 remains open until the second bimetal switch 3 is finally maintained in the open state by the radiant heat from the discharge tube 1 (about 2 to 3 minutes). The switch 3 repeats opening and closing operations, that is, the current in the series body of the second bimetal switch 3 and the resistor 5 is repeatedly interrupted, and the discharge tube 1 repeatedly blinks each time. Therefore, the second bimetal switch 3 is also connected to the resistor 5 and the discharge tube 1.
It must be installed at an appropriate location within the outer sphere 6, such that it is close to the outer sphere. On the other hand, it goes without saying that the first bimetal switch 2 must not be opened by the radiant heat of the resistor 5 before the discharge of the discharge tube 1 is established when the discharge lamp is started. However, the following problems have conventionally occurred when restarting the discharge lamp, that is, when the power is cut off and then turned on again while the discharge lamp is in operation.

う問題もあつた。 That is, when the power is turned off and turned on again during lighting, the second bimetal switch 3 returns to the closed state while the first bimetal switch 2 remains open, and this closing causes the ballast 7 to close. Even if a pulse voltage is induced in the discharge tube 1, the discharge does not start, and the second bimetal switch 3 continues to open and close. As a result, the life of the resistor 5 and the ballast 7, which are generally made of tungsten filament, is shortened. There was a problem with it being shortened. There was also the problem that the flashing of the light emitted by the resistor 5 was repeated for a long time, giving a feeling of discomfort.

の構造も複雑にならざるを得なかつた。 Furthermore, conventional methods have had the following problems. That is, conventionally, the first bimetal switch 2
A bimetal piece and a contact are attached to an independent insulator separate from the bimetal switch 3 and the resistor 5, and the second bimetal switch 3 and the resistor 5 are attached to the outer sphere axis within the outer sphere 6.
It was installed in the opposite position. Since both bimetal switches are installed independently, the installation position of the bimetal switch must be set each time during the assembly process of the discharge lamp, which not only takes a lot of time but also The structure also had to become complicated.

とにある。 An object of the present invention is to provide a high-pressure discharge lamp with a built-in starting device that is reliable in its operation at the time of starting and restarting, simplifies the installation of the starting device, and has a simple structure.
以下、本発明について一実施例を示す図面とと

The figure is a side view of the same, and FIG. 4 is a side view of the main part of a high-pressure discharge lamp in which this starting device is built into the outer bulb.

には同一番号を付している。 In the high-pressure discharge lamp of the present invention, the electrical connection between the discharge tube and the starting device is the same as that in FIG.
Further, in FIGS. 2 to 4, parts common to those in FIG. 1 are given the same numbers.

られている。 In FIGS. 2 and 3, a filament resistance wire (hereinafter referred to as a resistor) 5 is composed of a filament made of tungsten wire, and is wound and fixed around an insulator 9 made of a heat-resistant insulating material such as alumina. ing. This insulator 9 is a rectangular plate with a thickness of 2 to 3 mm, a width of 15 to 20 mm, and a length of 25 to 40 mm.
A plurality of grooves 9a for holding the resistor 5 are provided at regular intervals on two opposing sides. Furthermore, first and second bimetal switches 2, 3
Holes 9b and 9c are provided for fixing, and holes 9d and 9e are provided for attaching to support columns, which will be described later. Further, a window 9f for transmitting light is provided in the central portion.

バイメタルスイツチ3より離れて位置している。 As mentioned above, both the first and second bimetal switches 2 and 3 are attached to the insulator 9 using the holes 9b and 9c, but the second bimetal switch 3 faces a part of the resistor 55. On the other hand, the first bimetal switch 2 is placed a little away from the insulator 9 so as not to face the resistor 5. That is, the first bimetal switch 2 is located farther away from the resistor 5 than the second bimetal switch 3.

スイツチ3より放電管1から遠ざかつた場所に配
置される。 Thus, such a starting device is installed between two support columns 15, as shown in FIG. That is, the second and third connection terminals 13 and 14 are
It is connected between the support pillars 15 of the book, that is, between the power terminals. Further, one end portion of the starting auxiliary conductor 4 also serves as the first connection terminal 12. As you will see,
The first bimetal switch 2 is located further away from the discharge tube 1 than the second bimetal switch 3.

を要しない。 According to such a configuration, since the first bimetal switch 2 is provided at a position farther from the resistor 5 than the second bimetal switch 3,
It is less susceptible to the effects of radiant heat from the resistor 5, and therefore does not open before the discharge tube 1 starts discharging when the discharge lamp is started. Since the first bimetal switch 2 is also located at a distance from the discharge tube 1,
The temperature of the discharge lamp during operation is lower than that of the second bimetal switch 3, and therefore, when the discharge lamp is restarted, it always returns to the closed state before the second bimetal switch 3. In addition, since the first and second bimetal switches 2 and 3 are provided at different positions from the discharge tube 1, the contact pressure of both can be the same, and it does not take time to adjust the contact pressure as in the conventional case. .

なものとなる。 Furthermore, since the first and second bimetal switches 2, 3 and the resistor 5 are attached to the insulator 9, and it has three connection terminals 12, 13, 14, the starter can be attached to the support column 15. Afterwards, it is only necessary to connect the above-mentioned predetermined members to the connection terminals 12, 13, and 14, making the assembly work extremely simple.
